Cornual (interstitial) pregnancy, a very rare form of ectopic pregnancy, accounts for 2–4% of all tubal pregnancies in which
conception is located in the proximal interstitial portion of the fallopian tube. Cornual resection by laparotomy is generally
the preferred method of treatment, although more conservative approaches have also been described. We report a case of cornual
pregnancy that was successfully treated with a single dose of 100 mg methotrexate injected into the mass of the ectopic cornual
pregnancy. The serum human chorionic gonadotropin (hCG) level decreased to undetectable levels on the 60th post-operative
day. 相似文献
Background: High-sensitivity cardiac troponin T (hs-cTNT) is an important non-invasive laboratory-based marker of subclinical myocardial injury. Prehypertension, which may be a precursor of hypertension, is a major public health issue. Our aim was to evaluate the importance of serum hs-cTnT as a marker predicting prehypertension.
Methods: A total of 100 subjects (45 women and 55 men) consisting of 50 consecutive prehypertensive patients with blood pressures between 120/80 and 139/89 mmHg and 50 normotensive patients with blood pressures < 120/80 mmHg were enrolled prospectively. The hs-cTNT level was calculated and compared between the two groups. Echocardiographic examinations were performed in all patients.
Results: The hs-cTnT level was significantly higher in the prehypertensive group (p < 0.001) and was positively correlated with prehypertension (r = 0.625, p < 0.001). Hs-cTnT was an independent predictor of prehypertension (odds ratio = 1.043, 95% confidence interval [CI] 1.019–1.067, p < 0.001). An Hs-cTnT level of 0.55 ng/L was predictive of prehypertension with a sensitivity of 86% and specificity of 60% (area under the curve = 0.861; 95% CI, 0.787–0.935; p < 0.001).
Conclusion: hs-cTnT may complement other diagnostic biomarkers in predicting prehypertension.
Coronavirus disease 2019 (COVID-19) is a global pandemic affecting the world, seen in more than 1,300,000 patients. COVID-19 acts through the angiotensin-converting enzyme 2 (ACE2) receptor. Cardiovascular comorbidities are more common with COVID-19, and nearly 10% of cases develop myocarditis (22% of critical patients). Further research is needed to continue or discontinue ACE inhibitors and angiotensin receptor blockers, which are essential in hypertension and heart failure in COVID-19. Intensive research is promising for the treatment and prevention of COVID-19. 相似文献
Cortical blindness is a rare and dramatic complication of pre-eclampsia. The precise nature of the pathogenesis of this condition has not previously been understood. Three preeclamptic patients with unremarkable previous medical history presented with acute blindness between the 28th and 33rd weeks of pregnancy. They were all diagnosed as posterior leukoencephalopathy syndrome (PLES). In all these patients, MRI study revealed the typical feature of gray-white matter edema localized to the temporo-parieto-occipital areas. Vision and MRI findings were restored in all patients after delivery. Although PLES has been described as a puerperal clinicoradiologic entity, it may be seen in preeclamptic-eclamptic patients during the pregnancy. Therefore neuro-imaging studies should be carried out in pregnant patients with visual disturbances in order to exclude PLES. Prompt diagnosis, immediate control of blood pressure, and elimination of possible causes resolves clinical and imaging findings. 相似文献
AIMS: To describe the distribution of bone and joint involvement in 197 patients with brucellosis, and to detail a spectrum of findings on bone scintigraphy in 38 patients with brucellar spondylitis. METHODS: One hundred and ninety-seven patients (141 females, 56 males; age range, 5-77 years) with osteoarticular brucellosis were studied. Patients were classified into acute (62%) and chronic (38%) stages of the disease, and into age groups of less than 16 (1%), 16-30 (17%), 31-45 (29%), 46-60 (37%) and over 60 (16%) years. All patients were evaluated with Tc-methylene diphosphonate bone scanning. Quantification of sacroiliac joint uptake was performed to improve the sensitivity for the detection of sacroiliitis. Plain radiography and computed tomography (CT) or magnetic resonance imaging (MRI) were performed, when required, to evaluate the areas of the skeleton that showed abnormal uptake on the bone scan. MRI and single photon emission computed tomography (SPECT) were performed in all patients who had spinal lesions. RESULTS: The sites most commonly affected were the sacroiliac joints (53%) and spine (19%), followed by the shoulders (16%). Osteoarticular involvement was more common in females (72%) than in males (28%), and the acute stage (62%) was observed more than the chronic stage (38%). Bone and joint involvement occurred at any age, but the most common age group was 46-60 years. Eight scintigraphic patterns were identified in spinal involvement. CONCLUSION: Brucellosis may affect the musculoskeletal system at any site. Bone scan is a useful method to detect osteoarticular involvement in cases of relapse and progression. Spine involvement has the widest range of scintigraphic findings. A knowledge of the location and distribution of osteoarticular involvement as revealed on the bone scan of patients with brucellosis may be valuable in patient treatment and management. 相似文献
OBJECTIVE: The purpose of this study was to evaluate the screening performance of a new middle cerebral artery Doppler velocimetric index for the prediction of fetal anemia. STUDY DESIGN: Doppler velocimetry of the middle cerebral artery was performed before cordocentesis in 24 Rh-alloimmunized fetuses without hydrops on 52 occasions. The angle between the line describing the average slope during the diastolic phase of the cardiac cycle and the vertical, the middle cerebral artery standardized deceleration angle, was measured. The deceleration angle values were expressed in multiples of the median for gestational age. The screening performances of deceleration angle for the prediction of anemia (difference between expected mean hemoglobin level and measured value >/=2 g/dL) and severe anemia (hemoglobin deficit >/=5 g/dL) were determined. RESULTS: The mean (+/-SD) gestational age at cordocentesis was 28.6 +/- 5.7 weeks' gestation. The risk of fetal anemia increased with decreasing deceleration angle values. The sensitivity and false-positive rate for the detection of anemia in cases with no previous transfusions (one measurement per patient) were 72.0% and 13.3%, respectively; among those with one previous transfusion the values were 90.0% and 0.0%, respectively. For severe anemia the corresponding values were 100% and 0%, respectively, among those with no previous transfusions and 100.0% and 16.7%, respectively, among those with one previous transfusion. There was no risk of severe anemia when the angle was >0.9 multiples of the median. The risk of anemia was significantly reduced with an angle greater than the median for gestational age (deceleration angle >1.0 multiples of the median; relative risk, 0.09; 95% confidence interval, 0.02-0.37). The risk was significantly increased with an angle less than the median for gestational age (deceleration angle <1.0 multiples of the median; relative risk, 30.0; 95% confidence interval, 5.9-158.4). CONCLUSION: The risk of fetal hydrops is remote in the absence of severe anemia. With a new Doppler velocimetric index in the middle cerebral artery the risk of severe anemia was found to be low when the deceleration angle was >0.9 multiples of the median. Anemia can also be predicted with this index. The high sensitivities and acceptable false-positive rates support the potential clinical applicability of the method to reduce the reliance on cordocentesis in Rh alloimmunization. Our findings appear to validate the utility of the deceleration angle for the prediction of fetal anemia. 相似文献
